LOUM.

SLFEQ'IFIUATION forming part of Letters Patent No. 595,198, dated December 7, 1897.

Application filed May 22, 1897. Serial No. 637,661. (lie model.)

To all whom it may concern.

Be it known that we, J AMES H. NORTHROP and MYRON J. BIGELOW, of Hepedale, in the county of \Vorcester and State of Massachusetts, have invented an Improvement in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

While itis customary to locate the belt fork or shipper and the shipper-handle at the same side of the loomthe usual practiceitis de sirable at times to locate the shipper-handle at one side and the belt fork or shipper at the other side, and in United States Patent No. 574,143 a construction is shown whereby such object is attained. In that patent a spring is employed to move the shipperin one direction, movement in the opposite direction being effected by or through a flexible connection between the shipper and the shipper-handle.

This present invention is an improvement on the construction shown in said patent, whereby the spring is dispensed with and the shipper actuated in both directions by a posi tive connection with the shipper-handle, and the shipper-handle may be located at one side of the loom, with the belt fork or shipper at the other, or both may be located at the same side of the loom.

Figure 1 is a vertical side elevation of a-sufficient portion of a 100111 to be understood, embodying our invention, with the belt-fork and shipper-handle at the same side. Fig. 2 is a plan view of a portion of a loom, showing the application of our invention when the shipper-handle is at one side and the belt fork or shipper at the other side of the loom; and Fig. 3 is a detached side view of the shipper-handle.

The loom-frame A, breast-beam A, lay crankshaft B, the fast and loose pulleys B B respectively, on said shaft, and the pinion B are and may be of usual construction in looms.

Referring first to Fig. 2, the plate a is extended from one side of the loom, having aslot c and notch 6 theslot receiving the upper end of the shipper-handle Z), fulcrumed on a bracket or stand 5, secured to the 100111 side. At the opposite side of the loom a stud a, projecting therefrom, receives a sleeve a, carrying the usual belt-fork (0 an arm a on said sleeve traveling in a guide a on the loom side. The sleeve a has a stud a thereon to engage one end of a bent rod d, extended through an opening in the loom side, and a link (1 is rigidly secured to said bent red at its inner end, as by set-screws 2. The link is extended across the loom and through the opposite side frame and pivotally attached at d to one end of a lever (Z fulcrumed at cl on a stand (Z secured to the loom side. At its front end the lever d is bent up at (F, and its preferably reduced extremity (Z is loosely inserted in a slot b above the fulcrum b of the shipper-handle Z). (See Fig. 3.) Vhen the shipper-handle is released from the holding-notch 6 its spring S (see Fig. 1) will throw it into the position shown in Fig. 2, and through the lever (Z link, and red the belt-fork a will be positively moved to shift the belt onto the loose pulley B Movement of the shipper-handle into running position will positively move the belt-fork to shift the belt onto the fast pulley B.

Turning now to Fig. 1, the fast and loose pulleys are shown at the same side of the loom as the shippenhandle b, the loose pulley B outermost, and the stud a, a sleeve a, and belt-fork a with the guide a are also at the same side of the loom as the shipperhandle. The bracket (V has pivoted thereon a lever pivotally connected at (1 with the sleeve to; but in this instance the front end of the lever is downturned at (1 its extremity (Z being extended into a slot 11 in the shipper-handle, below the fulcrum of the latter. Such difference in the point of connection between the lever and the shipper-handle will now cause the outer end of the lever to be swung inward when the shipper-handle is released from the notch 6 to operate the belt-fork, instead of being swung outwardly, as in Fig. 2. This change is necessitated by the opposite movement of the belt-fork to shift the belt to the loose pulley 13 which in each instance is outside of the fast pulley B, as usual.

To adapt the mechanism from the construction shown in Fig. 1 to that shown in Fig. 2,

the connecting-rod d and link (1 are interposed between the belt-fork sleeve (4 and the lever on the loom side, and the lever d 615 (shown in Fig. 2) may be also used by merely turning it upside down, as shown by dotted lines, Fig. 1.

Having fully described our invention, what we claim, and desire to secure by Letters Patent, is

In a loom, a driving-shaft having fast and loose pulleys thereon at one side of the 100111, a belt-fork adjacent said pulleys, means to support it, and a shipper-handle having slots therein above and below its fulcrum, combined with a reversible bent lever at the same
